I seem to be having a number of issues with our SBS. I believe this was originally domain was previously on a SBS 2003 box before being moved to this SBS 2011 box last year, it has been running fine until yesterday. I cant see anything that has changed then though.

Everything seems to point to DNS although I am struggling to pinpoint the actual cause. The most worrying is when I try to open something on the SBS such as AD sites and services.

//edit can't post images yet - the error is

Do you see any "Automatic" start services that are either not running or "Paused"? I'm feeling like you've got a service not started that is preventing the machine from advertising itself as a DC. Did this start immediately after a reboot? What does the System Event Log have to say around the time that the problems started? –  Evan Anderson Jul 11 '13 at 21:55
    
I do have a couple of services that are not starting one is the DHCP server which stopped since this problem has occurred and wont restart... I am assuming that this will sort itself out once I fix the cause. Also the "Microsoft Exchange system attendant" service is not starting. –  Jase Jul 11 '13 at 22:02
    
How's the "Netlogon" service look, specifically? Can you describe what happened immediately before these problems started to occur? Did you load any updates, reboot the machine, etc? –  Evan Anderson Jul 11 '13 at 22:06
    
No reboot, or updates... Netlogon service is running (and set to automatic), it was one of things I checked as had seen others who had had an issue with it becoming paused or stopped all of a sudden. going through the logs again it looks ok then all of a sudden here is an error logged by group policy "The processing of Group Policy failed. Windows could not obtain the name of a domain controller. This could be caused by a name resolution failure. Verify your Domain Name System (DNS) is configured and working correctly." event ID 1054 –  Jase Jul 11 '13 at 22:19
    
Does the view in the DNS Management Console look normal? You're seeing your _msdcs.contoso.local forward lookup zone and it appears to be populated normally? –  Evan Anderson Jul 11 '13 at 22:23

To resolve this I ended up restoring the sysvol folder from a backup. I am not sure if this was the best way to fix it but it worked.
